Hopefully described with my other answer :)

This patch set is not trying to support the electronic device
PL111 at all. I am trying to support an emulator which has a
half-done emulation of the PL111 registers.

The other panels actually attached to real world instances
of PL111 made in silicon, all have proper drivers in
drivers/gpu/drm/panel already.

All real electronics are already covered. They use:
drivers/gpu/drm/panel/panel-arm-versatile.c
drivers/gpu/drm/bridge/dumb-vga-dac.c

All QEMU emulators are already covered (by making
QEMU emulation behave like real hardware). It now
uses DDC by way of dumb-vga-dac.c.

This virtual display in this emulator is the missing final piece to
convert the PL111 fbdev driver over to use DRM.

Yours,
